'APPARATUS Eonv TEE'ATING IIQUIDs.

To all whom it may concern.'

Be it knownV that We, FREDERICK N. BEYER and JOHN H. LOUNGE, citizens ofthe United States, residing at Chicago, in the county of Cook and S'tateof Illinois, have invented certainnew and useful Improvements inApfparatus for Treating Liquids, oflwliich the following is adescription.A

Our invention belongs to that general class of devices kno'vvnasapparatus for treating liquids, together With the method of treating theliquids, and relates particularly to a method and apparatus for treatingmilk or the like so as to preserve the same. T he invention has amongits objects the production of a method and apparatus of the kinddescribed that is simple, efficient, economical, convenient andsatisfactory for use Wherever found applicable. Many other objects andadvantages of lthe method and apparatus herein shown and described Willbe obvious to those skilled in the art from the disclosure hereingiven.

To this end, ourY invention consists in the novel method, construction,arrangement and combination of partsvherein shown and described and moreparticularly pointed out in the claims.

In the drawings, wherein like referencev characters indicate like lorcorresponding Parts. j Figure 1 is a View in elevation of our improvedapparatu s," a portion being shown diagrammatically; Y l

Fig. 2 is a sectional-vie through one Vof Fig. 3' is 'a sectional viewnthroughtthe treating tank Fig. 4 is asectional view throughthe Sprayer#t; V- f y Fi`g15 is atop elevation ofthe-sprayer;

' Fig. 6 is a fragmentary sectional View taken substantially on line6,-6 of'Fig; 2.'

Referring to the drawings, 1 represents a tankprovided With'an'intakepipe 2 and a discharge pipe 3, the same'beingppreferably arranged at thebottoni, as Ashown in Figs. 1 and The tankni'salso preferably providedwith anv air outlet at 4 having a suitable valve which may be shut-'asdesired. Arranged on the interior of the 'tank 1 and connected with theintake pip'e'2y isa pipe 5 Which is provided With a sprayer 6, formedSpeccatioiiof Letters Patent.: gttgentqgd Niay 17 1921. Application l'edMay 28, 1918'. Serial N0. 237,103. y' i with a top 7, provided withholes or perforations 8 therethrough. The particular size, shape anddesign of the tank and sprayer, as Well as the number of holes,'may beas desired.

Arranged on the tank 1 are What-may be termed ozonators 9, theseconsisting of suitable Walls 10 at the sides, top and bottom, closed atthe end 11, and positionedat the lopenings 12 in the side Wall of thektank 1. Extending to each ozonator is an air pipe- 13, through which airis admitted as Will be hereafter described. Arranged Within the ozonatorand insulated from each other are plates 14 and 15, which are providedwith binding posts 16 and17, or their equivalents. Also arrangedon theozonator are conductors or plates 18. As shown, these adjusted asdesired.` Y Y Air pipes 1,3 are connected by pipes 21, 22 and 23 With anair pump 24 of suitable design, or theequivalent for vthe purpose. lWealso prefer to provide a pressure regulator 25 and a'gage 26, so thatthe desired air pressure may be maintained so as to control thecirculatie-n of air through the ozonators to produce 'the most eflicientresults. The binding posts 16 and 17 are connected with a high' voltagetransmission'line, as shown by conductors 27, 28, 30, 31 and 32, with atransformer seconda-rvA 29.V The transmissionline 34-35 is' connectedWith'tlie primary 33, 36 being a rheostat so thatv the electricalldischarge from the ozonator may be as desired.` Y f i ntake pipe 2 isconnected by pipe`37 connected With a tank 39 containing untreatedmilk,underpres,sure, which is forced fromV the pipe 37 and intake pipe 2into tank '1, 38 being a valve for controlling `the passage ofthe'same'.l rl`he tank 39 is connected With a receiving tank 41 forunti't-iated ini-lk, which receives `itslsupply. from a feed pipe 42. Asshown, tanks 39v andv 41 are connected by pipe 40, it ybeing understoodthatany equivalent construction may be employed. The compressor, or airpump, or source of supplyof air 24 is connected to tank 39'by V'pipe43,44 being a pressure gage Which is preferably 'employed As mostclearly shown in Fig. 1, We preferably place a check valve 45 in pipe 40so that the contents of tank 41 can flow into tank 39, but not from 39into 41.

In operation, milk is fed into tank 41, flows into tank 39 and is forcedby the air pressure through pipe 37, past valve 38, through pipe 2,kpipe .5, sprayer 6, out through the holes 8, the same breaking orspraying the milk Vinto a very fine mist. At the same time air is forcedthrough pipes 13, through ozonators 9, into the tank 1, into the milkmist or spray. The voltage of the line 34-v35 may be as desired,ordinarily 110 volts, but the voltage of the lines 27, 30. and 31 fromthe secondarywvinding 29 to the transformer is ordinarily from 7,000 toV10,000 volts, this being controlled by the rheostat or regulator 36.The air from pipes 13 passing through the discharge between'plates 14and 15, and baffled back and forth, forms ozone, which enters into tank1 Where the milk or like fluid mist is, thereby ozonating` the milk,Which drops to the bottom ofthe tank and flows out through dischargepipe 3 to Where desired. Ve have found from experiments thatparticularly satisfactory results may be obtained when the milk isthoroughly sprayed or broken up to form a mist, the same in this casebeing thoroughly impregnated or treated with the ozone. tion isconcerned, the lactic acid germs in the milk are presumably killed andthe milk keeps for a considerable number of days beyond the periodduring which' it would ordinarily keep Without treatment. Vhile theapparatus is particularly intended for the treatment of milk, fruitjuices and other liquids might be treated in the same manner so as toprevent the liquids from fermenting, becoming rancid or deteriorating.

Having thus described our invention, it is obvious that variousimmaterial modifications may be made vin the same Without departing fromthe spirit of our invention,

Ahence We do not Wish to be understood as limiting ourselves to theexact form, construction, arrangement and combination of parts hereinshown and described or uses mentioned.
